The Pacific Northwest is a unique geologic area. Layers and layers of rock, ash and soil, formed over millions of years, tell the stories of volcanoes, earthquakes, floods and glacier movement. Within these layers there is also evidence of human activity, buried forests and ancient animals. Have you every wondered why there are so many beautiful waterfalls on the Oregon side of the Columbia River Gorge but not on the Washington side? Or, why are so few dinosaur fossils found in the Northwest? You’ll find the answers in the videos of CWU professor Nick Zentner, below.
